Press the MENU key twice to access the Main Menu
System and then press the RIGHT Cursor key to select the
Sonar tab, which contains the following menu choices
when you are in Normal User Mode:
Fish ID+
TM
uses advanced signal processing to interpret
sonar returns and display a Fish Symbol when very
selective requirements are met. A number above the fish
icon indicates the depth of the fish. Three different fish
size icons show the intensity of the sonar return, and
provide an indicator of relative fish size. When Fish ID+
TM
is turned off, the Matrix shows only the unprocessed
sonar returns on the display. These returns will often
result in "arches" forming on the display, indicating
potential targets.
Fish Sensitivity adjusts the thresholds of the fish detection algorithms, thus
enhancing your unit’s ability to identify sonar returns as fish icons. Selecting a
higher setting allows fainter returns to be displayed as fish icons and will increase
the number of fish icons that appear on the display. This is useful for identifying
smaller fish species or baitfish. Selecting a lower setting displays fewer fish icons
from faint sonar returns. This is helpful when seeking larger species of fish.
Bottom View selects the method to display bottom and structure on the display.
Structure ID® presents the graphical representation of the bottom and structure
sonar returns using only grayscale to indicate the signal strength. WhiteLine®
highlights the strongest sonar returns from the bottom to make a distinctive outline
of the bottom contour, structure and fish. Bottom Black displays all pixels below the
bottom contour as black, regardless of signal strength.
RTS® Window turns the RTS® window on or off in the Sonar View.

Press the MENU key twice to access the Main Menu System and then press the
RIGHT Cursor key to select the Sonar tab, which contains the following additional
menu choices when you are in Advanced User Mode:
Surface Clutter adjusts the filter that removes surface clutter noise caused by
algae and aeration. The lower the setting, the less surface clutter will be displayed.
(Low = 1, High = 10, Default = Low)
Noise Filter adjusts the sonar Noise Filter to limit interference from sources such as
your boat engine, turbulence, or other sonar devices for best display performance.
(Off, Low, Medium, High, Default = Low)
NOTE: The Off setting removes all filtering; Low, Medium and High settings add
progressive filtering of the sonar returns. In some deep water situations, the High setting
may actually hinder your unit’s ability to find the bottom.
Water Type configures unit for type of water conditions. (Salt, Fresh, Default = Fresh)
NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger
than a large fish in fresh water (depending on the type of fish you are seeking). The salt
water setting allows for a greater range in fish size adjustment to account for this. Also,
make sure that the Water Type is set accurately, especially in salt water, as this can affect
the accuracy of deep water depth readings.
Max Depth adjusts the maximum depth of unit operation. (Auto, 10 to 1200 feet,
Default = Auto)
NOTE: The performance of your unit can be tuned to the maximum depth you will be
fishing in by setting this menu choice. When a maximum depth is set, the unit will not
attempt to acquire sonar data below that depth, thus increasing overall performance.
When the Max Depth is set to Auto, the unit will acquire bottom readings as needed
(within the capacity of the unit).
